I v Application tiled Dccouiherld, 1885. Serial No.'186,0'-19. (l\'o nimlnl.)' I

To all whom it may concern: Be it known that I, FRANK Runs, of the city and State of New York, have invented an Improvement in Repeating Fire-Arms, of which the following is a specification.

i The present invention'relates to improveset forth in" my application, No. l62,'546,filed to the said application for a general description and mode of operation of the respective reference made useof herein refer to corre- Inmy present improvement I make use of a tridges has been exhausted, and I combine with the said stop and carrier a clampingscrew to hold the end'of the follower i it its proper position, and make, the gun a singlei firing arm, so that the carrier may be revolved 5 and the cartridgestsupplied one at a time by and sear-spring with reference. to allowing the out firing it, and I combine with. the trigger arm being fired should the tumbler have becoming exhausted, and I combine with the door of the ejecting-chamber a peculiar axle, crank-arm, and spring for closing said door,

inserting cart-ridges separately by hand.

In the drawings, Figure lis an elevation with thelock-plate' removed. Fig. 2 is a crosssection near the line as. a: atthe rear of the bar-f rel and the follower of I the magazine, and theparts connected therewith; Fig. 3is asection near the line 3 y of Fig.2, showing the-rear end of the barrel and part of the magazinetube in section.

Fig. 7 is anele-' vation of the stationary-lock-fran e and parts conaectedwith it. Fig. 8 is across-section at the linezz, Fig.7. Fig.9 is a partial crosssection at the line y" y, Fig.7. Fig. 10 is a detached view of the revolving tumbler, trigger, and parts connected therewith. Fig. 11 isa cross-section ot the housing and of one of ing tumbleraindthelblockingpiece upon the trigger. Fig 'l2 is an elevation, and Fig. 13-- is a section, of, the extension'n agazine below the barrel. Fig. 14 shows apportion of the chain, and Fig. 15 is apartial plan showing the lockingrshaft and apart of the firing-sear.

The chain H passes from the chain-wheel near'the butt of ,the stoclrbeneath the-pulley H. and to the chain-wheel T,;that gives motion tothe tumbler as in my aforesaid application, but I construct the chain of'longand short links, the long'links beingin pairs and the short links occupying intermediate positions, as shown in Fig. 6, and in the detached view, Fig. 14, the object of this construction being the toggles, andarear elevation of the revolv- 7 to obtain the spaces necessary for the teeth of the chain-wheels,-sotha't said teeth may project up between the linlisl l andcome against the ends of the links 22.. In this manner theteeth are made sufiicientlylarge to obtain the necessary strength, and the links of the chain are straight'and not liable either to slip upon the chain-wheels or to break in consequence of the sudden stopping and starting of the arts.

In Fig. 6 I have shown a helical spring,H within the tube H, and having a follower, H", and a, chain, H, to the fuses-barrel H upon the winding-shaft h; This chainH" preferably passes around a pulley, H3", so as to obtain the desired length for-the tube H containing theexpansive helieal spring H. The end of the chain is attachedto, the barrel H, wherethei'usee-is'of the largest diameter, hence the power of the spring is nearly equalized, because as the spring is compressed and becomes more powerful the chain is wound upon a smaller part of the-barrel.

The tumbler K andthe parts connected withjthe same that revolve the carrier-and "L are properly placed and held by the stud v rect position.

n is made in the manner next described.

.in cases where the spring is nearly exhausted Y thest-ud 1* upon the cam i may not have sufticient power to press the toggle-links I. L g upwardly against the action of the spring Z, and if the arm should be discharged while in I this position the breech-bolt might be blown back. I therefore provide upon the hooked l -endf of the trigger F a blocking-piece,f", Y

projecting as an arm that comes at its end close against the cogs 7 upon the rear of the tumbler K; but when the tumbler K receives .its entire movement and the toggle-links L i, the end of the blocking-piecefswingswith the trigger and passes in under and below the' lower toot-h, 7, upon the tumbler K in the act of discharging the piece, but the trigger cannot be moved when the tooth T is in line with r the end ofv the blocking-piece f. The end of this blocking-piece f" may be slightly inclined so as to press beneath the tooth 7 upon the tumbler -K, and partially raise the same in cases where the parts are very near to the cor- The action of the trigger F. trigger-sear S, trigger-latch S, sear n" for the-firing-pin, and the parts connected with the same correspond to those set forth in the aforesaid application except that thejointed end Mor the sear arm The spring :2 acts against an incline upon th'esear end n, and at the joint 27 there/is a shoulder upon the sear end n", and a latch, 21*; upon the sear-arm n, which, taking against i the shoulder upon the sear end it causes the sear-arm and sear to bemoved by the triggerl sear S in firing the gun, If, now, the shaft t 5 is turned in one direction by the finger pie'ce I f, the safety-lock i. is brought against the sear end 11', as in the aforesaid application, and locks the parts so that the trigger cannot be 5 moved and the gun cannot be tired; but if the finger-piece t and shaft i are moved in the other direction the arm if comes against 3 the latch if, unlatching the end from the} shoulder of the sear n, and at the same time forming a blocking piece that holds the 'seararm 21 above the hinge-joiht- 2T firmly.

sear S swings the scar end n npon its hinge 27. At the same time the revolving tumbler K is liberated, and all the parts are free to be moved except the firing-pin; hence under these circumstances a cartridge can, be withdrawn from the barrel and the carrier revolved, and the cartridge ejected without bej ing exploded. 1

In my aforesaid application a lock-frame, I is recessed to form the filling and ejecting? chamber M, and the spring-door m swings upon the hinge-pin 12, and there is a helical spring for closing the door. I find .it prefer- 1 able to connect the hingepi'n and the door l together by a square upon the hinge-pin en 1 If, now, the trigger is pulled, the end of its l l tcring a similar opening in one knuckle of the doorhin'ge, and at the end-of, said hinge. pin 12 I make use of a crank-arm, 30,'(see Figs. 7

and 8,) against which crank the flat'spring 3i bears and turns the pin 12 to close the door in,

and this door at is opened by theejcotor I,

j that is hung from the. hinge-pin l2 and provided with a shoulder against the inner face of the door at, and the finger 14 upon the axis r acts against the ejector P to move the same for throwing outthe cartridge case or shell, and at the'saine' time the door at is'op'ened by the shoulder upon the ejector. The axis 2" is provided with the arm 1', against which the.

cam i acts, as in my aforesaid application.

When the cartridges are being supplied by hand into the chamber )I, it is convenient to hold the door in open. I accomplish this by means of aspring-catch, n, upon the side plat'e,'E'. (See Fig. 9.) This spring-catch m passes into a mortise in the fingenpiece m of the door m and the springcatch yields to allow the door to close when suificientpressure is applied to the door. The follower o is within the magazine tube 0, and againstit the spring 0 acts to move the cartridge along into the revolving carrier.' 7 Upon this follower 0' is a ring-flange, 1, and the stop-piece c and finger-piece c are provided as in said application'to prevent the follower a passing out into the revolving carrier. \Vhen the cartridge hasbeen conveyed away by the car- .rier from the magazine, the end of the follower o' ro'ectin into the carrier rereuts P J g the same. being "revolved. I combine along with this stop 0 and the finger-piece c a grai ity-latch, c ,.occupying aslotin the stem of the stop'c. (See Figs. 3 and i.) This gravity-latch drops into the position shown in Fig. 3and prevents the finger-piece c" being moved forward when the fire-arm is held in a horizontal position, because the end of the gravity-latch drops over and catches against v a portion of the housing. If, now, the fire-arm is held in a vertical positio nthis gravity-latch will hang out of theway of the housing, and the finger piece c and stop 0" can be moved so as to drawthe follower 0 out of and away from the spent-cartridge shell, because itdrops by gravity back into the ejecting-chamber 1L 1 when cartridges are supplied one at a time 'the spent shell'is ejected. The .screw 0 can be screwed in behind the last cartridge in the magazine,so as. to retain the cartridges therein "sary range of motion an additional spring;

,as a reserve when required, and allow the arm to be used as a single-firing gun.

lnmany instances it is importantto increase the capacity .of the magazine, especially in view of the rapidity withwhich this gun can be tired,

.In Figs. 12 and 13 I have represented a magazine extension-tube G, the same having a socket to slip over the outside-{of the mega-- zine-tube G, and there is a spring-clip, C or other fastening device to connect the magazine extension-tube to. the magazine. This allows for the introduction of a large number of car-' tridges, and the spring 0 of the ordinary magazine and the follower a pass into this mega zine extension-tube, and to obtain the neces c,is provided within the magazineextensiontube G. magazine extension tube may be pointed atthe outerend and 1 provided wit-ha crossrpiece, 0, near the inner end to allow for its use as a weapon, if needed. A movable cap is to be provided for the end of the magazine-tube 0 when the extension-tubeisremoved,and lalso find that it is important to keep moisture out of the barrel; In cases where corksor plugs have been made 'use of they are liable to be lost. I form the outer end of the barrel with a slightly-tapering bore of a sizeto receive a spent-cartridge caseso that such a case can. be used as aplug, and I find that it is much bet ter thap the plugs heretofore used because it is absolutely water-proof, and can be pulled out or replaced with great facility.

I find that it is preferable to make use of a steel plate at the end 26 of the sear S, because the same is ez'rposed to both concussion and wear; but it is preferable toinsert a plate of brass or copper between this steel plate and the end of the sear, in orderthat the comparatively soft metal may accommodate itself to the surfaces of the steel and act'as a cushion in lessening concussion. Similar plates may be placed at the inner surfaces of the trigger-hookf. p

I claim as my invention- 1. The combination, with the tumbler K and the lock mechanism of the fire-arm operated by the tumbler and the spring, of a chain madeof short; links introduced between longer links, and the chain-wheels having pro- As a matter of convenience, this tjecting teeth that pass-in between t'liepairs of longer links and acting against the shorter links, substantially as specified.
